The CAS Registry Mumber 141901-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,0 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141901-28:
(8*1)+(7*4)+(6*1)+(5*9)+(4*0)+(3*1)+(2*2)+(1*8)=102
102 % 10 = 2
